You don't know jack is a fun, fast paced computer game for two to four players on your PC. I have found that the game is also available on most PS1, PS2 systems also. The object is simple-get in teams, or individual players, answer the barrage of questions thrown your way and try to accumulate the most points by the end.
The pace of the game is rather fast-perfect party game. The questions are difficult-they are usually covering obscure, random information on a variety of difficult subjects-these are not easy, fluff kind of questions. There are numerous mini-games in the game also, but the format stays the same.
Overall, a great game for a party of people looking to show off their knowledge or lack there of and have a fun time with it. The best part are the random comments and insults the computer throws out to you.
